To all whom it may concern:

Be it known that I, CHARLES F. DoEBLER,

a citizen of the United States, and a resident of New York city, in the county of New York and State of New York, have invented,

certa in new and useful Improvements in Dam Constructions, of which the following is a specification. i

My invention relates to constructions of concrete reinforced with metal, and has for its principal objects to adapt such construc- 7 tion for use for retaining-walls, dams, and the like. v

My invention consists in the arrangements and combinations of parts, substantially as hereinafter described and claimed.

'In the accompanying drawings which form a part of this specification, and wherein like symbols refer tolike parts wherever they occur. Figure 1 is a vertical sectional elevation of a structure embodying my invention, and discloses a dam construction,

the deck of which is formed at an angle to its base as-illustrated. Fig. 2 is a plan view of a portion of the deckshown partly in section and discloses the method of reinforcing the same. Fig. 3 is an inverted-plan view disclosing the arrangement of the but-' tresses. Fig. 4 is a portion of the deck shown partly in vertical section and illustrating the construction at the point where side.

the deck and buttresses mcet' Fig. 5 discloses a portion of-the construction .as it appears when viewed from the downstream In practice the several portions of my construction will be built in one continuous mass of concrete by'the use. of molds or false work, as is usual in concrete construction.

' 3 The principal featureimprovement consists in. the arrangement 'of the reinforcement which consists of metal bars em.- bedded in theslab-likedeck in such a man nor as to form ,a cantaliver construction when the deck is completed whereby the length, of the bars which extend longitu I dinally of the deck may beinade of com struction I also embody the use of iron bars paratively' short sections and .may'span a distance'equal to orQl ess than the distance between the supporting walls. In my con which are embedded in the deck and extend the'entire width thereof, 'andby arranging my longitudinally extending bars both above and below the laterally extending bars I am able to provide a very solid construction which will 'resist the expansion and contraction due to the water either cov-- ering the deck or only partially covering the same, which is set up in all such structures where the same is exposed to hot and cold currents of air.

interlock at the points C where they merge with a portion of the buttresses which extend. in alinement with. the flow of the stream which port-ion is indicatedby C. The result of this arrangement of the buttresses is to form spaces between the same at the point where the deck is supported thereby, which spaces show the greatest width between the points C Where the walls join and which spaces greatly'decrease in width as-they approach the apex of the an gle in each direction.

In order to save material, cost and time in construction it has been found that the walls or buttresses may be spaced, so that the distance across from the junctionC to the opposite junction C" may be considerably increased if the deck is properly reinforced with iron rods or by the use of cor-bels: and metal or by the combination, of both, and to this e d I have arranged t'or s such reinforcement, as follows? "In Figs, 3 and' i, I haveshown'thelebrb el constructionfarranged just under the deck:

C. and indicated .by etcapwhich corbels extend toward each other asclearly; shown in Fig. 3, so that the span'betweenl the points: 0?, C is reduced to a certain ea} tent.

Thc iron rods-indicated by extend the full width of the-dam as -illus-";-. trated in'Fig; l and indicatedin dotted lines I in-Fig. 2 and are spaced apart from each other throughout-the entire lengthjof the *1 dam but are shown broken off in the draw; lugs-1n Fig. 2 so' as not to cause confusion fic cated below the bars E, and are spaced nearer together near the middle of the spaces than is required at the points Where the said bars extend entirely across, so that the ends rest above the walls B.

The walls B may be spaced sufliciently .near together so that the corbels will not be needed and in this case the bars G are extended almost entirely to the walls near the middle of the spaces and overlap the said walls near the ends of the spaces as illus' trated in Fig. 2.

The bars G are perferably about one inch in'diameter and are spaced apart from each other near the center of the span about slx inches from center to center, but these 'measurements as to size and spacing will necessarily depend on the height of the dam and the pressure-of water that the deck is to sustain, so that I do not wish to limit myself to the size or relative spacing of the bars as to distance.

By the relative arrangement of concrete and reinforcing means above pointed out, a

" construction can be produced which will. suc- 'cessfully withstand the changes of temperature, and the walls may by this system be spaced a considerably farther distance apart. where a dam 1s used without such lell'lfOlfie ment.

It will be observed that by reason of the fact that the rods F are run the entire length of the dam and the rods E run the entire width thereof, that a complete crosswork is provided at all points in the deck where the distance between the reinforce ment comprises a. small rectangular space indicated by a square H in Fig. 2, and that the spaces between the walls where further reinforcement is necessary is supplied by the rods GGG, etc, and that by this arrangement of rods a complete cantaliver construction provided in the deck.

Since the pressure of water is lessnear the top of the dam than nearer the bottom thereof, it has been found unnecessary to extend the V-shaped walls the entire Width of the dam, and I. therefore, arrange to have the walls B-B merge together and form one continuous. wall from the point C to the rear end of the buttresses, and by this con st-ruction I am able to reduce the amount of concrete which will be necessary without the walls extended separately to the ends of said abutments aswill bereadily understood.

In order to provide for the escape of water from between the walls in case any tresses and a deck formed integral therewith,
